Study Notes
Properties of Life
- Organisms exhibit enabling characteristics such as energy intake, responsiveness, and reproduction.
- A constant internal environment (homeostasis) is not a property of life.
Hierarchical Organization of Life
- Biological hierarchy from least inclusive to most inclusive: molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem.
- Tissues are components of organ systems.
Ecosystems and Energy Flow
- A community consists of various organisms interacting within a specific area.
- Energy flows from producers (e.g., plants) through consumers in ecosystems, primarily in one direction.
- Chemical nutrients cycle through ecosystems, unlike energy that flows and dissipates.
Genetics and Diversity
- Genetic variation among organisms results from differing nucleotide sequences in DNA.
- Bacteria form their own domain, distinct from Archaea and Eukarya.
Classification of Living Organisms
- Kingdom Animalia: Organisms consume other organisms for nutrients.
- Kingdom Fungi: Decomposing organisms that absorb nutrients from dead matter.
- Kingdom Plantae: Photosynthetic organisms.
Evolution and Adaptation
- Beneficial adaptations arise through natural selection; organisms with advantageous traits are more likely to reproduce.
Experimental Design
- In experiments, the experimental group receives the treatment, while the control group does not.
- Valid experimental results necessitate awareness of initial conditions and variables.
Research Applications and Observations
- Evidence of life can be substantiated through responses to environmental stimuli, reproduction capability, and cellular processes.
- Comparison of ecological parameters aids in understanding restoration processes.
Pesticide Resistance
- Insect species resistance to pesticides has increased significantly from 1900 to 2000, indicating evolutionary pressure on the population.
